  • Patent number: 10466040
    Abstract: A sensor device (100), for measuring a surface (101), includes a lighting device (103) emitting a light beam (105); an optical device (107) splitting the light beam (105) into partial light beams (109, 111), and emitting the first partial light beam (109) toward a first surface area (113) and emitting the second partial light beam (111) toward a second surface area (115). A light sensor (117) is configured to receive a first surface area reflection (109-1) of the first partial light beam (109) and a second surface area reflection (111-1) of the second partial light beam (111). A processor (119) is configured to detect a distance of the first surface area (113) and of the second surface area (115) to the sensor device (100) based on a position of the first partial light beam reflection (109-1) and the second partial light beam reflection (111-1) on the light sensor (117).

  • Patent number: 10401474
    Abstract: A sensor array includes a housing with a circumferential housing wall, which defines a housing opening, with a sensor circuit board with a high-frequency sensor. The sensor circuit board in the housing is arranged such that the high-frequency sensor is directed towards the housing opening. A one-piece closing cap closes the housing. The one-piece closing cap has a circumferential cap wall and a high-frequency lens. The high-frequency lens closes the circumferential cap wall on the front side and is directed towards the housing opening. A distance between the high-frequency lens and the high-frequency sensor and thus a focal length is predefined by a lateral length of the cap wall.

  • Publication number: 20190029167
    Abstract: A sensor device for determining a position of seeds while sowing. The sensor device includes a radiation assembly which generates an illumination radiation oriented towards a target area, and a detection assembly. The radiation assembly includes a radiation source which provides an emission spectrum of the illumination radiation covering a spectral range. The detection assembly includes a radiation detector which detects an incident radiation, and a filter member with an attenuation band and a pass band. The radiation detector includes a field of view. The pass band has an attenuation which is less than an attenuation of the attenuation band in a wavelength range where the wavelengths are longer than those of the attenuation band. The target area and the field of view intersect. The radiation source and the radiation detector form a triangulation arrangement so that a distance from the target area to the detection assembly can be determined.

  • Publication number: 20180332840
    Abstract: A control device for controlling a height of a boom of a vehicle. The control device includes a transmission/receiver set, a processor, a control, and a communication interface. The transmission/receiver set transmits an initial measuring signal and receives an initial reflection signal in response thereto, and transmits a second measuring signal and receives a second reflection signal in response thereto. The processor determines a majority of initial reflection components of the initial reflection signal, a majority of second reflection components of the second reflection signal, and compares the initial reflection components with the second reflection components to determine matching reflection components. The matching reflection components indicate a layer of reflection objects. The communication interface links the processor with the control and to determine a control signal for controlling the boom based on the matching reflection components.

  • Patent number: 7579580
    Abstract: An optical sensor (1) with a light beam (7) created by a pulsed primary light source (5), which light beam is reflected at a surface (13) of an object and is recognized by a detector. In order to mask interfering effects, which might develop due to diffused light of the light beam (7), a compensation light source (25) emits a light cone during station breaks in operation of the primary light source (5), which includes the diffused light range of the light beam (7) of the primary light source (5). In this way, objects within the diffused light area create a compensation light portion, which prevents the activation of the sensor output merely by the diffused light of the light beam (7).

  • Patent number: 6784441
    Abstract: A manually controlled sensor for authenticity identification of luminescent identification features on documents is described, in which the identification feature is illuminated with an excitation wavelength and may respond at a different wavelength, with the response wavelength being detected and evaluated by a radiation receiver. In order to improve the sensitivity and to comply with the safety at work regulations, a focused beam (31, 32), which is emitted from a beam source (1), is converted by focusing optics (2, 3) in such a manner that a scanning bar (22), which is approximately in the form of a line, is projected on the surface of the object (5) to be investigated, which causes the identification region (21) which is arranged on the object (5) to fluoresce in a luminescent manner in at least one subregion, and the luminescence signal produced in this way is passed via detection optics (9, 9′, 10) to an evaluation unit (11), which evaluates the luminescence signal.

  • Patent number: 6600380
    Abstract: A known oscillator with a 2-terminal coil without a tapping has only a limited dynamic controllability and apart from this is unsuitable for implementation in CMOS technology. The oscillator, first of all is extended by a current mirror. By the addition of the current mirror Q3, Q4 and additional power supply sources, one achieves a greater dynamic controllability and the suitability for implementing it in CMOS technology. By means of the excitation of the oscillating circuit with switched current sources Io, one achieves the proportionality of the oscillation amplitude to Rp and Io. In practice more complicated structures are used for switches and current sources. With this, an additional controllability of the oscillation amplitude independent of the damping of the oscillating circuit is obtained. The method is-used for distance measurement. The additional control of the oscillation amplitude is utilized for the correction of the manufacturing tolerances and of the temperature-dependence.
